The Myth of Shocks
An Excerpt from Chapter 1 of The Socionomic Theory of Finance

By Robert Prechter

Few people find a new theory accessible until they first see errors in the old way of thinking. Part I of this book challenges the universally accepted paradigm under which humans' rational reactions to exogenous (external, or externally generated) causes purportedly account for financial market behavior. The current chapter explores whether dramatic news events affect financial markets.

Testing Financial-Market Reaction under Perfect Conditions

In the physical world of mechanics, action is followed by reaction. When a bat strikes a ball, the ball changes course.

Most financial analysts, economists, historians, sociologists and futurists believe that society works the same way. They typically say, "Because so-and-so has happened, it will cause such-and-such reaction." This mechanics paradigm is ubiquitous in financial commentary. The news headlines in Figure 1 reflect what economists tell reporters: Good economic news makes the stock market go up; bad economic news makes it go down. But is it true?

In the second half of the 1990s, a popular book made a case for buying and holding stocks forever. In March 2004, after several terrorist attacks had occurred, the author told a reporter, "Clearly, the risk of terror is the major reason why the markets have come down. We can't quantify these risks; it's not like flipping a coin and knowing your odds are 50-50 that an attack won't occur."1
